They may look like pats of butter now, but these pups are being trained by veterans with PTSD to one day provide assistance to injured service members.

These six golden retriever puppies are more than just adorable balls of fur — they’re working to heal the invisible wounds of U.S. combat veterans.

Known as Holly’s Half Dozen, the future service dogs are being petted and socialized by recovering service members from the Walter Reed National Military Medical Center in Washington, D.C., and the National Intrepid Center of Excellence in Bethesda, Md.

And you can watch them live 24 hours a day for the next eight to 10 weeks on explore.org.

The litter of five girls and one boy, all born to a golden retriever named Holly on June 24, will spend the next two years lifting the spirits of wounded veterans by providing them with a therapeutic and purposeful mission.

Veterans work with the dogs through Warrior Canine Connection, an organization that helps service members with both physical and psychological injuries. The trainers who socialize the dogs are combat veterans with post-traumatic stress disorder, or PTSD, and the people who receive the trained service dogs are veterans with mobility-limiting injuries.

The live webcam was launched by nonprofit multimedia organization explore.org and Dog Bless You, a group that pairs war veterans with service dogs. The camera is part of explore.org’s Pearls of the Planet initiative that aims to reconnect humans with animals and nature.
